I don't have cable, so this Roamio basic is set up as OTA only. I've had it for a little less than a year, and it has been pretty much flawless. Until this evening, that is, when I tried to access my pre-recorded OTA content and the screen went black and the Roamio became unresponsive.

If I push the TiVo button, it makes the familiar 'ding' sound, but the screen remains black and nothing else happens. No other remote pushes are acknowledged by the TiVo. After ~5 minutes or so, it reboots.

This has happened about 6 times now. I can't get any recorded OTA show to play. They just hang.

Pushing Live TV doesn't display anything either, and going to the Antenna Test Signal Strength screen and trying to access the meter also hangs the box.
